Overheight Detection System monitors vehicles height and warn drivers if their vehicle exceeds the maximum height for the approaching overhead structure, whether that be a tunnel entrance, low bridge underpass or a gantry sign.

When an overheight vehicle is detected by the system, the electronic warning signs and flashing lamps are activated. If connected, it can also trigger an audible alarm in the central control room. The detectors are capable of detecting overheight vehicles traveling at up to 100 km/h, even in rain, snow, or dusty conditions. Overheight Detection Systems are proven to minimize or eliminate the occurrence of incidents caused by overheight vehicles.
